Jewish law prohibits Lashon hara (gossip), rechilus (talebearing), mesirus (slander), malshinus (defamation) and motzee shem ra (character assassination). I don’t suppose it has ever occurred to you to boycott news sources that practice these things.
Furthermore, in the secular system, there is the presumption of innocence, and “hearsay” is not valid evidence.
I will give Agri “dan l’kaf sechus” over PETA and the lynch mob media.
You are correct. That would have been the correct thing to do Jewishly.
